Half-Life 2

Underhell in my opinion, the greatest story driven Source mod I have every played! You don't even need Half Life 2 to play it, just install the Source SDK Base 2007 in your Tools. If you want replaybability, an itriguing story, frightening horror elements, impeccable atmosphere, fun combat and stealth, and around 15 hours of gameplay (did I mention that it is fully voice acted?), you owe it to yourself to download and install this 1.6 gigabyte mod. This mod was created with such passion and such care that I just have to spread the word. You can check out the mod at this page here: http://www.moddb.com/mods/underhell. If you immensely enjoyed this mod like I did, tell your friends and vote for it on Greenlight. Everyone should play this mod!
